There are few things in the entire Universe that are as terrifyingly awesome as a black hole. To have a region of space exist that contains gravitational forces so strong that literally nothing can escape it (whether it’s a particle, light, or any electromagnetic radiation for that matter) seems like a concept straight out of … Continue reading What’s in a Black Hole? → Continue reading → Continue reading
“Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. Though wise men at their end know dark is right, Because their words had forked no lightning they Do not go gentle into that good night. Rage, rage against […] Continue reading
Albert Einstein was one of the most influential thinkers regarding the fabric of the universe. Einstein’s major contribution to modern physics was his theory of relativity. The first part of this revolutionary idea was his special theory of relativity. Published in 1905, it established two major points: the laws of physics are the same in … Continue reading Blog #2: Special Relativity → Continue reading → Continue reading
How fast is light? Nothing on earth is known to move faster, and in my opinion, we are actually very fortunate to be able to measure it. Aside the fact that light enables us to see, I am appreciative of it even more because if it were to get any faster by any stretch, astronomers … Continue reading Can we travel at the speed of light? → Continue reading → Continue reading
Have you ever imagined what it would be like moving at the speed of light? To have the ability to travel that quickly (think ~300,000,000 m/s) would be incomprehensible — you’d experience a host of different effects, including time dilation (how more rapidly moving objects experience time more slowly), relativistic aberration (how your field of … Continue reading Traveling at the Speed of Light → Continue reading → Continue reading
The speed of light is one of the few constants in our universe that we consistently look to when it comes to space. It is an astronomical measurement that we only dream of achieving. Seeing the Millennium Falcon shift into overdrive or the Enterprise slip into hyperdrive are only distant fantasies for us Earth-bound creatures. … Continue reading Kessel Run in Twelve Parsecs → Continue reading → Continue reading
The theory of special relativity tells us that there is an absolute speed limit in the universe, that being the speed of light. At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading → Continue reading
Spacetime is often described as a “fabric”, but there is one theory that would describe it as more like sea foam- made of a bunch of tiny bubbles. This is the quantum foam theory. The quantum foam theory basically came into existence to try and unite Einstein’s theory of relativity and quantum mechanics, something that […] Continue reading → Continue reading
Can you believe it? The semester and the year are nearly over, and while I have plenty to look forward to (the holidays, meeting my dog again, catching up on hundreds of hours of sleep), there is a lot to look forward to in the world of science fiction… Continue reading
Because everyone deserves a happy ending. (Continued from The Old Equations, by Jake Kerr) March 1, 2194—LC-E transmission Kate, your final message inspired me, but it is so hard to sit here and just wait. And wait. And wait. I’ve kept the QE link from Earth open, even though nothing ever comes through. Still, I […] Continue reading
